The technical program is by being fixed on brace panel the leading portion of left front longeron, and forms cavity body structure with it, and this cavity body structure can play the absorption impact load, strengthens the crash-proof performance of left front longeron.
In the additional strengthening of the above-mentioned left front longeron of a kind of automobile, described left front longeron is the groove shape beam that is shaped on groove structure, and described brace panel is made as the groove shape structure that matches with left front longeron.In the technical program, brace panel can be fixed in the groove structure of left front longeron, left front longeron is played the effect that strengthens intensity.
In the additional strengthening of the above-mentioned left front longeron of a kind of automobile, connecting portion one that the brace panel of described groove shape comprises respectively and the groove two ends are affixed and connecting portion two, and affixed connecting portion three of bottom portion of groove and groove between constitute the isolation part of cavity.In the technical program, brace panel is by being fixed on its two ends on the left front longeron, and isolation part in the middle of it and left front longeron form a crash-proof cavity.
In the additional strengthening of the above-mentioned left front longeron of a kind of automobile, the leading portion Joint of the leading portion of described brace panel and left front longeron, the posterior segment Joint of the back segment of described brace panel and front side member.
In the additional strengthening of the above-mentioned left front longeron of a kind of automobile, be shaped on the welding knock hole on the described brace panel, described brace panel and left front longeron are fixing by welding.Be provided with the welding knock hole in the technical program, the location confirmation when being convenient to the installation of brace panel and left front longeron is to guarantee the correct of position of weld.
In the additional strengthening of the above-mentioned left front longeron of a kind of automobile, described brace panel and left front longeron are affixed by bolt.By bolted connection, further strengthen the Joint strenght of brace panel and left front longeron in the technical program.
In the additional strengthening of the above-mentioned left front longeron of a kind of automobile, described brace panel is shaped on the limit wing of undaform.The technical program adopts the limit wing structure of undaform, so that welding.
In the additional strengthening of the above-mentioned left front longeron of a kind of automobile, be shaped on cavity on the described brace panel.By cavity is set, increasing the section at this place, thereby increase its load-carrying capacity in the technical program on brace panel.
Compared with prior art, the utility model is simple in structure, easy for installation, it is optimized left front longeron brace panel structure, by the increase to the change of section structure and overlap joint scope, the data after the optimization have been strengthened the intensity that the bending deformation position takes place longeron, have guaranteed the absorption of the stable and collision energy of longeron distortion in head-on crash, the deformation pattern of longeron is become in collision rationally, ensure passenger's safety.
